piperazine-2-carboxamide;dihydrochloride

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of di-tert-butyl 2-carbamoylpiperazine-1,4-dicarboxylate (7.5 g, 22.79 mmol), in HCl/MeOH (75 mL, 2.86; N) was stirred at room temperature for 16 h. The mixture was concentrated in vacuo to yield the product (4.58 g, 100% yield) as a yellow solid. The mixture was concentrated in vacuo
